There are indeed 2 metrics with the same label "Conversions". However, their property_key is different:
- Conversions (m_conv1_loads): This metric gives you the number of times a page declared as a goal page has been loaded, i.e. the number of loads of the goal page as in Analytics Suite 2.
- Conversions (m_conversions): This metric takes into account the number of loads of the goal page as well as the sales events: (st.)product.purchased (sends an event when a product is purchased), (st.)transaction.confirmation (sends an event when a transaction is confirmed).
